Hi, I have a customer that hosts multiple email domains and wants to setup the autodiscover.domain.x for there domains. They have one single CAS 2007 server internet facing. In order to just use one cert public cert with autodiscoer.domain.x, is the following correct procedure.. 1. Creat public A cert autodiscover.domain.x 2. Create DNS A record for autodiscover.domain.x pointing to public IP x.x.x.x. 3. Create SRV records for all email domains point to autodiscover.domain.x on port 443 Will the above work for Internet clients and without any cert errors? Or is there something Im doing wrong or missing? ThanksCeltic

Hi First question, Is this for a hosted exchange environment or a normal setup?Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

It is not hosted. It is just for a single exchange server which has multiple email aliases for users. So users have different email aliases. I have read further that I do not need an A record for autodiscover.domain.x but I can use the domain name they currently use for OWA and point the SRV records to that on port 443. Am I correct? ThanksCeltic
